A satellite revolves around the earth in a circular orbit with a velocity “v”. What is the total energy of the satellite? Let “m” be the mass of the satellite.

A satellite revolves around the earth in a circular orbit with a velocity “v”. What is the total energy of the satellite? Let “m” be the mass of the satellite. Correct Answer – (m*v2)/2

Total energy (E) = KE + PE KE = (1/2) x m x v2 PE = – 2 x (KE) = – m x v2 E = (1/2) x m x v2 + (- m x v2) = – (1/2) x m x v2.
